Answer:
In 14 months, both providers will cost $1010
Step-by-step explanation:
Provider A costs 65 per month along with a 100 setup fee. You could write that as a slope-intercept equation, c = 65m+100
Provider B costs 70 per month along with a 70 setup fee. You could write that as a slope-intercept equation, c = 70m+30
You can put the two equations together, which would be 65m+100=70m+30. With simple algebra, you would get 5m=70. m would equal 14. So, after 14 months, the providers will cost the same. Now you can substitute 14 as m to find the price. c = 65(14)+100 = 1010. So, after 14 months, both providers will cost $1010.
